Module
Feature
Description
Memory Demand and Patrol
Scrubbing
Corrects errors upon detection. If these
errors are not corrected promptly,
uncorrectable errors may occur.
Memory Mirroring
Improves system reliability.
Single Device Data
Correction
Provides a single-device multi-bit error
correction capability to improve memory
reliability.
Device Tagging
Degrades and rectifies DIMM device faults
to improve DIMM availability.
Data Scrambling
Optimizes data stream distribution and
reduces the error possibility to improve the
reliability of data streams in the memory
and the capability to detect address errors.
PCIe
PCIe Advanced Error
Reporting
Improves server serviceability.
UPI
Intel UPI Link Level Retry
Provides a retry mechanism upon errors to
improve UPI reliability.
Intel UPI Protocol Protection
via CRC
Provides cyclic redundancy check (CRC)
protection for UPI packets to improve
system reliability.
System
Core Disable for Fault
Resilient Boot (FRB)
Isolates a faulty CPU core during startup to
improve system reliability and availability.
Corrupt Data Containment
Mode
Identifies the memory storage unit that
contains corrupted data to minimize the
impact on the running programs and
improve system reliability.
Socket disable for Fault
Resilient Boot (FRB)
Isolates a faulty socket during startup to
improve system reliability.
Architected Error Records
With the enhanced machine check
architecture (eMCA) feature, the BIOS
collects error information from hardware
registers in compliance with UEFI
specifications, sends the error information
to the OS over the APEI of the Advanced
Configuration and Power Interface (ACPI),
and locates the error unit, improving system
availability.
Error Injection Support
Injects errors to verify various RAS
features.
